The trail is really beautiful, but it more or less ends in front of a pasture. It's barricaded with barbed wire. I'm not sure if the fence is just meant to keep the cattle in or also keep bikers and hikers out. Since there's no way around it, we made it through. The alternative would have been to push the bike back.

Castelsardo - Sardinia from a picture book In the northwest of the island of Sardinia, Castelsardo sits high above the coast - a town straight out of a picture book. It envelops its visitors with all its charm, supported by old fortress walls and colorful houses. Castelsardo is part of the association of the most beautiful places in Italy, I borghi più belli d'Italia - and not without reason!
